The relation can be routed from one box
to
another in three different shapes (see
Figure 1):
- "C" shape for outer
connection of the box top to top, left to left, right to right and
bottom to bottom.
- "L" shape connects top/bottom to left/right sides of
the box.
- "S" shape connects left to right and top to bottom.
The relation routing shape is selected by the hint point place. There
is the area for every shape. When the hint point is in the specific
area, the relation is
always has the particular shape.
